The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the manufacture of spare parts, identified as "16--SLEEVE." This procurement is a sole source requirement, indicating that the government does not possess sufficient data to contract with any source other than the current supplier, and requires Government Source Approval prior to award. The items are critical for military operations, necessitating compliance with stringent quality assurance standards, including ISO9001-2000/AS9100B. Interested vendors must submit their proposals by August 22, 2025, and can direct inquiries to Danielle Junod at danielle.m.junod.civ@us.navy.mil or by phone at 215-697-1138.
